Line clock (when working as DTE interface) and internal clock (when working as
DCE interface).
Four types of test measures: local cell loopback, local loopback, remote payload
loopback, and remote line loopback.
Note:
You may equip your router with ROUTER 1-PORT T3 ATM FIC cards to its full capacity. Yet, you are
recommended to install only one ROUTER 1-PORT T3 ATM FIC on it, whatever its model is, to ensure
performance of some key services.
